    "title": "COSHAIR: UK Integrated Assessment Model (UKIAM) Maps of PM2.5 and NO2 Concentrations",
    "abstract": "The Community Scenarios Of Hydrogen Energy And Impacts On Air Pollution (COSHAIR) examines a range of scenarios from 01/01/2020 to 01/01/2050 with different levels of hydrogen take-up, in different sectors, to understand the consequences for air pollution. The scenarios investigate the potential implications of hydrogen production and use in the energy system on UK air pollution. These scenarios were produced using the UK TIMES energy system model at University College London. This represents all substantive UK energy flows and greenhouse gas emissions. \r\nThe UK Integrated Assessment Model (UKIAM) at Imperial College was used to examine the changes in air quality that might occur in the future due to adopting hydrogen in the scenarios. \r\nData contains the ASCII files, compatible with QGIS, for the spatially apportioned UK concentrations of PM2.5 (particulate matter with a diameter of 2.5 micrometres or less) and NO2 (Nitrogen Dioxide) using the UKIAM framework. \r\nThe supporting information provides full descriptions of the scenario names:\r\n\r\nNDB - No Decarbonisation Baseline (no hydrogen, non-net zero)\r\nNZC - Net Zero Counterfactual (net zero, no hydrogen)\r\nLS - Likely Scenario (net zero, limited hydrogen)\r\nLPS - Likely and Possible Scenario (net zero, higher hydrogen)\r\nUS - Unlikely Scenario (net zero, highest hydrogen)",
